Abstract:Size distributions of mass concentrations and chemical components in Hangzhou atmospheric particles were determined. The chemical components consisted of organic carbon (OC) and elemental carbon(EC), 11kinds of water-soluble ions, and 20kinds of trace elements. The size distributions of mass concentrations appeared significantly a bi-modal with peaks in the particles with size of <0.49μm and 3.00~7.20μm, respectively, as well as those of chemical components of OC, EC, SO42-, NO3-, K+, Na+, Cl-, Ca2+, Mg2+, NO2- and F-. The OC, EC, SO42-, NO3-, NH4+ and trace elements of Cu, Zn, As, Se, Sb, Cd derived from anthropogenic sources mainly focused in fine particulate matters (<3.0μm), so this suggested that a serious secondary pollution existed in the fine particles, and the fine particles were mainly affected by the anthropogenic sources derived from industrial and traffic pollutions.
